Altus NR3

Compact GNSS Rover for Surveying & GIS Applications

  • Robust, light and portable GNSS receiver
  • Quad-constellation, multi-frequency, all-in-view RTK positioning
  • AIM+ anti-jamming and monitoring system
  • Easy setup and one-touch logging
  • All-in-one base and rover operation
  • 4G/LTE connectivity

 

The Altus NR3 combines easy-to-use, multi-frequency, quad-constellation RTK with an unrivalled communications toolset for a successful survey or GIS project every time. It incorporates leading GNSS and wireless technology into a sleek and compact design.

AIM+ anti-jamming and monitoring system

AIM+ offers built-in protection against intentional and unintentional jamming using a sophisticated system of sampling and mitigation mechanisms. The Altus NR3 can suppress the widest variety of interferers from simple continuous narrow-band signals to the more complex wide band and pulsed transmitters as well as lnmarsat and Iridium satellite transmissions. 

The GNSS+ toolkit - Septentrio’s suite of algorithms to convert bad measurements into good positioning

Mechanical vibrations or shocks caused by rough terrain can wreak havoc with satellite tracking. LOCK+ automatically adjusts the tracking loop parameters of the Altus NR3 Smart Antenna so you never lose position.

Activity in the ionosphere is a problem for GNSS signals, from loss of RTK fix to total loss of signal lock. Having honed our skills in the most iono-active areas on Earth, the result is IONO+: the most advanced protection against ionospheric disturbances to GNSS signals on any receiver.

Metal and large nearby structures can reflect GNSS signals and produce multipath. The APME+ system disentangles direct and reflected signals enhancing both position and measurement quality. APME+ is bias free and, in line with Septentrio’s commitment to maximum configurability, can be disabled.

Advanced Receiver Autonomous Integrity Monitoring (RAIM+) comprises fault detection mechanisms of the receiver at all the levels including the generation of measurements, quality control and navigation algorithms. Detected faulty measurements, which are typically caused by high multipath or active ionosphere, are removed from the solution.
